Distinctiveness (1=highest,4=lowest): 4
(nationally important)
This region contains some of the remnant prairie dog ecosystems which support
predators including the endangered black-footed ferrets.*

Conservation Status (1=most endangered, 5=most
intact): 3 (vulnerable)
Because of the aridity of the region which prevents cultivation, and the
remoteness from human population centers, many areas have remained relatively
intact. Conversion from sagebrush habitat to reasslands for domestic
grazing has degraded some areas severely. Few areas are protected, and
overgrazing, fire suppression, invasion by exotic grasses are threats.*
